To all whom it may concern.'

Be it known that I, Animar ANDRES, a citizen of Germany, of 84 Vaiblingerstrasse, Cannstatt, Vurttemberg, German Republic, have invented certain new and useful Im proveniente in Cutting Devices, of which the following is a specification.

My invention relates to cutting devices and more especially to devices connected with shoe pegging machines for cutting olf the ends of the wooden pegs which are proj ected through the sole of the shoe.

The majority of shoe pegging machines nowadays in use are provided to this end either with a reciprocating chisel. or with a rotary cutter, the inner sole serving as an abutment in both cases. However the sole does not offer the necessary resistance and it therefore frequently happens that thc pegs bend or break within the sole, thus rendering the fixation of the sole inferior. Inga certain type of pegging machine the cutting tool has the form of nippers whose action is superior to that of the above mentioned appliances,4 But owing to the restricted space available in the forward end of the arm or horn carrying them they have to be kept so slender that they tend to break easily, especially so in the case when they accidentally come in contact with one of the iron pegs.

The cutting tool according to my invention although adopting in a general way the forni of nippers, differs from the devices described above in that its cutting jaws instead of being fixed to a pair of scissors, are arranged on the circumference of a tubular socket and of a pin arranged in said socket respectively.

In the drawings ailixed to this spscilication and forming part thereof two modilications of a cutting device according to the present invention are illustrated, Figure l being a longitudinal section, Figs. 2 and 3 crosssections on the lines A--B and C-D respectively, of one modification, F ig. l showing the same without the casing as viewed from the front. Figs. 5, 6 and 7 are a longitudinal section and two cii'ossfsections on the lines F-G and Ici-3, respectively, of another modification.

In the hollow end a of the work supporting arm or horn there is arranged a sleeve or hollow socket Z) having a pin c inserted therein. The forward portion of socket Z) is cut away, leaving a part CZ of crescent secgrasp the points z' of the pegs projecting outwardly from the sole /L (Fig. l) and cut them off cleanly close to the sole. The parts carrying the cutting edges may be actuated by different means. In the device shown in Figs. l to el lever arms le and Z are fixed to the parts and c respectively, and a wedge a is fastened to the free end of a rod m which, when moved in the direction of the cutters against the action of a spring' 0, will cause the arms and Z to be spread apart and the parts (l, e to revolve around their common axis, thus forcing the cutting edges f, c7 against each other. t

In the modification shown in Figs. 5 to 7 the cutting edges, instead of being forced apart by a spring, are guided back to their initial position by means of two angle levers Q oscillating around an axle p, and linked` at one end to the wedge a, while the other ends are in Contact with the lever arms 7c, l. lVhenever the wedge is pulled back, the angle levers press against the outside of `arms le, Z and thereby cause the nippers te open.

I wish it to be understood that my invention is not limited to the exact form and construction of the parts shown and described. Thus the cutting edges, instead of being arranged on the circumference of the parts l), c, may as well be disposed either below or above the circumference.

I claim:

l. In a device of the character described, in combination, a work-supporting arm, a hollow cutting edge carrier carried by said arm and extending substantially longitiidinally of it, a second cutting edge carrier concentrically arranged within the iirstnamed carrier, and means for imparting to at least one of said carriers a movement about their common axis.

2. In a device of the character described, in combination, a. work-supporting arm, a hollow cutting edge carrier carried by said arm and extending substantially longitudinally of it, a second cutting edge carrier coneentrically arranged within the first-named carrier, means for imparting to at least one of said carriers a movement about their common axis, and means for returning said carriers to their initial position.

3. In a device of the character described, in combination, a work-supportin arm, a hollow cutting edge carrier carrie n by said arm and extending substantially longitudinally of it, a second cutting edge carrier concentrically Varranged within the firstnamed carrier, and means for imparting to said carriers a movement about their common axis in opposite directions.

4. In a device of the character described, in combination, a work-supporting arm, a hollow cutting edge carrier carried by said arm and extending substantially longitudinallyroffit, a second cutting edge carrier concentrically arranged within the firstnamed carrier, cutting edges opposite each other arranged on said carriers, and means for imparting to at least one of said carriers a movement about their common axis to bring said cutting edges together.

Y 5. In a device of the character described, in combination, al work-supporting arm, a

hollow cutting edge carrier carried by said arm and extending substantially longitudinally of it, a second cutting edge carrier concentrically arranged with the first-na med carrier, an arm on each of said carriers, and means for spreading said arms apart to move at least one of said carriers about their common axis.

6. In a device of the character described, in combination, a work-supportin arm, a hollow cutting edge carrier carrie by said arm and extending substantially longitudinally of it, a second cutting edge carrier concentrically arranged within the firstnamed carrier, an arm on each of said cnrriers, means for spreading said arms apart to move at least one of said carriers about their common axis, and means for returning said carriers to their initial position.

In testimony whereof I aiix my signature in presence of two witn.
